wINDsHIELn CLEANER.

Application filed May 8,

This invention relates to a windshield which includes a plurality of spaced apart wipers extending vertically across a w1nd-.

shield pane and reciprocated'edgewise in contact with the pane by an oscillatory cranl arm, the wipers being adapted to collectively wipe a large area of the pane. I

The chief ob'cct of the invention is to en sistance, and a minimum expenditure of,

force. 7

Of the accompanying drawings forming a r part of this specification-,-

Figure 1 is a fragmentary perspective view, showing a windshield cleaner embodying the invention, the windshield and portions of the tracks and crank-arm hereinafter described being omitted, the cleaner including two wipers.

Figure 2 is a front elevation of awindshield and a cleaner embodying the invention associated therewith, the cleaner including three wipers.

Figure 3 is a fragmentary section on line 33 of Figure 2.

Figure 1 is a fragmentary section on l ne HofFigure2.

Figure 5 is a fragmentary section on line 5-5 of Figure 2.

The same reference characters indicate the same parts in all of the figures.

In the drawings 12,12 designate horizontally extending tracks in fixed relation to the frame 13 and pane 14 of a wlndshield, the tracks being preferably flat sided metal strips or bars, attached at their ends preferably to the frame 13, by fastenings 15, the tracks being offset from the outer side of the pane 14, as indicated by Figure 3.

16' designates a rock-shaft ]OLlI11&lGCl n a bearing above the pane 14, the bearing being, in this instance, in the top memberof the frame 13. The rock-shaft is provided with a crank-arm 17, which is spaced from the outer side of the pane 14, as shown byFigure 3, and is oscillated in a plane parallel with said pane by turning movements of the rock-shaft.

An element of the cleaner is an oblong grid which is reciprocated in a rectilinear path by the oscillation of the crank-arm and is provided with a plurality of wipers 18 of compressible material, such as rubber, bearing on the outer side of the pane 14.. I

The grid includes a channeled middle 1928. Serial No. 27 045.

cross-bar, wiper-carrying end cross-bars, each. cross-bar being provided at; Its. ends with runner, portionsslidably engaged Wi'th the tracks, and tie-rods 19, rigidly connecting the:

cross-bars.

The channeled middle cross-bar includes two spaced apart side portions 20, which may be connectedbya neck portion 21, andeach end cross-bar is a single strip22, the tie-rods 19 extending through the several cross-bars,

and being rigidly attached thereto. The

wipers 18 may be attached to :the cross-bars by any suitable means.

The runner portions of the preferably provided by forming slots 23 in the ends of the cross-bars, the tracks 12 extending through the slots. I

In the embodiment shown by Figures 2, 3, 1 and 5, the channeled middle cross-bar is provided with awiper 18, so that the grid has three wipers, while in the embodiment shown by Figure 1, only two wipers 18 are provided.

The tie-rods 19 maintain the channeled middle cross-bar midway between the end 1,688,386 PATENT OFFICE.

cross-bars 3.13%

cross-bars. The inner faces of the side por- I tions 20 of the channeled cross-bar constitute spaced apart abutm-ents with which a terminal 25, on the crank-arm 17, is slidably engaged, said terminal being in this instance, an

angle to the major portion thereof, and bearend portion of the crank-arm, bent at an ing on said abutments, so that when the crank-arm is oscillated, its terminal 25 bears i and slides first on one of said abutments, and then on the other, to reciprocate the grid on the tracks. The side portions 20 and the terminal 25 constitute a suitableembodiment of connecting means adapted to impart re-' ciprocating movements from the crank-arm to the grid. I

In c-onsequence of the location of the middle cross-bar midway between the end crossbars, the location of the described connecting less than would be required if" the channeled cross-barwere at one'end ol'i thegrid.

WVhen the windshield 1s relat vely wide and the crank-arm is relatively long, two wipers 18 are sufiicient, each wiper being adapted to slightly overlap the track made by the-other.

When the Windshield is relati ely narrow,

' and it is desired to wipe iractically the entire length of the pane, three wipers are reniredl In Fi iire 2 the extreme ios'itions' b of the grid are indicated by Ltulland broken lines,and the rocln'shat't-is located atthe mid length of the frame 13K The rock-shaft 1'2 may be rocked by any suitable means, which n'i'ay include a well known motor '28, oper ate'tl s'ii ction exert'cbby a motor yeh'ic'le engine, and *a ma'nuallyOperable handle 291' .The'windshie'lfdframe may be'e'ithe r fixed,
